Christina Aguilera Goes Back to Classy in ‘You Lost Me’ (VIDEO)

Christina Aguilera is ditching her sexified persona and going back to a more demure, lady-like look in her new video for ‘You Lost Me,’ the second single off her album Bionic.

In the video, Aguilera slows down the tempo and shows off her vocal chops with the ballad, all while circling a sheet-less mattress.

The Lost video is a far cry from her first video off of the album. In ‘Not Myself Tonight,’ Aguilera transformed back into her dirty — err, ‘Dirrty’ — personality with a whole bunch of skimpy outfits and over-the-top sexuality.

Watch the You Lost Me video below, and tell us in the comments which Christina you prefer: Dirrty or clean?
